Trying to find the Euclidean distance of 2 vectors with different sizes

T = [

5.1000 3.5000

6.4000 3.2000

5.4000 3.4000

5.7000 2.8000

5.7000 4.4000

5.6000 2.9000 ];

X = [

5.5000 3.8000

6.4000 2.9000

4.3000 3.0000

5.4000 3.0000

4.5000 1.5000

1.1000 0.1000

1.1000 0.1000 ];

I'm trying to find the euclidean distance between each row of T and each row of X.

This is the method that I have been using to find the euclidean distance and to store the results into an vector, within a nested for loop.

for i=1:1:size(T)

for j=1:1:size(X)

distance( i ,1 ) = sqrt( (( T( i , 1 ) - X ( j , 1 )).^2 ) + (( T( i , 2) - X( j , 2 )).^2) );

end

end

T =[5.1000    3.5000 
    6.4000    3.2000  
    5.4000    3.4000   
    5.7000    2.8000   
    5.7000    4.4000  
    5.6000    2.9000 ];
X =[5.5000    3.8000  
    6.4000    2.9000  
    4.3000    3.0000   
    5.4000    3.0000    
    4.5000    1.5000
    1.1000    0.1000
    1.1000    0.1000 ];
D = pdist2(T,X)
